6 Claims. 1

This invention pertains to a sink receptacle or the like, and, more particularly, to a combination sink drain cover and a receptacle cover separately operable over a refuse receptacle positioned in the waste outlet of a sink, lavatory or similar plumbing fixture.

It is an important object of this invention to provide a sink refuse receptacle providing the novel feature of a receptacle with a by-pass for water in combination with both a receptacle cover and a sink drain cover.

Another object of this invention is to provide a sink refuse receptacle located in the sink waste outlet or drain line and mountable therewithin on the usual sink drain openings. Aswill hereinafter become readily apparent, the entire construction is mounted in the sink drain to be positioned completely below the base level of the sink and, therefore, in no manner impeding the use of the sink.

Other objects and advantages will become more readily apparent upon proceeding with the following description read in light of the accompanying drawing, in which Fig. 1 is a sectional assembly view of a preferred embodiment of this invention.

Fig. 2 is an enlarged sectional view of the covers and actuating portion thereof relating to the structure shown in Fig. 1.

Fig. 3 is a sectional view of the cover engaging mechanism taken on the line 3--3 of Fig. 2.

Similar reference numerals refer to similar parts throughout the several views.

As shown in Fig. 1, this invention is preferably mounted within a drain outlet for a sink l hav- 1 ing the usual opening H in the bottom thereof, and the remainder of the sink which is not shown should be understood as being of the conventional type. Also, the sink opening H may be the size of the usual drain opening existent in the normal sinks. snugly located in the opening II, and preferably depending therefrom, is a cylindrical spud member 52. The latter member may be provided with an upper annular outwardly flanged portion I5 to engage a corresponding recessed portion in the sink and support the reeeptacle structure which thus depends from the sink, as illustrated.

A substantially central outer portion of spud I2 is threaded for engagement with a threaded spud nut or joining ring l3 located substantially under the sink In to retain a gasket it therebetween and thereby form a fluid tight seal.

An outer portion of the ring I3 is preferably threaded to engage an upper inner surface of a ingor refuse receptacle 2| depending cup-shaped member or outercasing H. The lower central portion of the member I! is open and suitably attached to a downwardly extending drain pipe I8 which leads to the usual trap and lends support to the entire receptacle structure. A strainer [9 may be provided in the lower opening of member I l to thereby catch any excess refuse which may enter the strainer.

Spaced within the member I! is an inner caswhich is preferably supported therewithin by the member l2. Thus, the support is provided by an upper outwardly flanged receptacle edge 22 annularly abutting a lower inwardly flanged edge 23 of the member [2. It should be apparent that the receptacle 2l could be supported within the member H in a number of other arrangements, such as a more direct attachment to the member ll. It is preferred that the receptacle 2| be provided with a plurality of apertures 25 in the bottom thereof for the purpose of refuse draining from within said receptacle.

A pivotally mounted receptacle handle 24 is attached to an accessible upper portion of the receptacle to facilitate removal of the latter from the member I! when desired.

7 It should be understood that the receptacle member may be of an inexpensive material, such as a cardboard or composition container or a cloth bag, and thus be easily and relatively cheaply disposable.

An important feature of this invention resides in the construction of the member [2 and a drain closure cover 26 and a lower receptacle closure cover 27 which are normally disposed within the spud member I 2. An inner annular portion of the member i2 is shouldered, as at 28, to form a seat for the drain cover 2'6. Thus, it will be apparent that liquid is prevented from passing from the sink basin when the cover 26 is placed in position on the annular seat surface 28. An annular wall portion of the member l2 below the seat 28 is provided with a plurality of apertures 29. It will be apparent that the last referred to lower portion of the member I2 could be entirelyeliminated if the receptacle 2| had a more direct support from the member [1.

The receptacle cover 2'! is normally seated upon the receptacle flanged end 22 to form a liquid'seal with the receptacle.

As shown more clearly in Figs. 2 and 3, the respective upper and lower covers 26 and 21 are connected by means including a handle or actuating member 3| having a lower threaded portion extending through a central opening 32 in the cover 26. A lower hollow link member 33 is preferably internally threaded to engage with the lower threaded portion of the handle 31. The handle 3! may be provided with an annularly flanged portion above the threaded portion and thereby shoulder with the cover 26 to secure members 26, 3|, and 33 together as shown. An annular gasket 34 is preferably disposed between the handle shoulder and the cover 26 to form a fluid seal therebetween.

The lower surface of the link member 33 has two oppositely inclined surfaces 35 for reasons hereinafter described in detail.

An upper portion of the cover 21 is provided with a fixed wedge shaped boss member 35 which aligns with the link member 33 to position the link surfaces 35 and the boss wedge surfaces normally in juxtaposed cooperative relation. A screw 37 is threaded into the boss 35 and the screw head extends upwardly into a central chamber formed in the link member 33 to be limitedly movable axially therewithin and thereby join the covers 26 and 21 with predetermined clearance or lost motion. Thus, it will now be clear that in the removal of cover 26, the cover 21 is also removed.

It should be noted that the normal respective seated positions of the covers 26 and 2'! determines the space between them, which, of course, insures seating of the top cover 26 without being supported and held off the seat by link member 33 abutting boss 36.

The relation of the inclined. and wedge surfaces on the members 33 and 36, respectively, thus exists for the desirable function of rotating the link member 33 through 90 degrees and thereby unseating the cover 26. In the above mentioned position, the link member 33 is supported on the uppermost surface of the boss 36 (see Fig. 3). The cover 2'! remains seated on the receptacle 2!.

It should, accordingly, be apparent that such described rotation of the handle 3| will permit the seating or unseating of the cover 26. The how of water past the cover 28 may thus be controlled and permitted to pass through the apertures 29 flowing outside of and around the receptacle 2| and into the drain or waste outlet pipe is Since the cover 2'! remains seated, no water will be allowed to pass into the receptacle 2!, and only by removal of the structure with the covers 28- and 21, will the receptacle be open to receive water, garbage and similar sink refuse.

In summary, it will be clear that a comparatively simple, economical, and sanitary sink waste outlet with an easily disposable refuse container has been devised capable of being installed in new and old installations with a minimum of inconvenience and expense. It also possesses the advantage that, if desired, the container 2! may be suitably flushed by merely raising the cover 21 from its seat on the flanged portion 22 of the said receptacle upon suitable actuation of the handle 31.

Although this invention has been shown and described in but one specific form, it should not be so limited as it is susceptible to changes within the spirit of this invention and the scope of the appended claims.
